Information processing system

Abstract

Abstract PURPOSE:To easily find the cause of trouble in its early stage by collecting state information on internal states of devices of this system when abnormality occurs and sending it to an information processor which has a display means. CONSTITUTION:If abnormality is detected at the side of a microprocessor 11, data in a storage area in a memory which is judged to be abnormal are transferred to the working storage area in the memory 12 and transmitted to the microprocessor 1 together with additional identification information which shows an abnormal end request. The processor 1 checks data received by a reception part 8 and starts an abnormality processing program stored in a memory 6 if detecting the identification information showing the abnormal end request. The abnormality processing program interrupts the current processing of the processor 1 and displays the current contents of all registers in the processor 1 and the contents of the storage area in the memory 6 which are used for the current processing on a display part 5 through a display control part 2. An operator recognizes the abnormality occurrence at this point of time.
